Which two tools can be used to recover an inconsistent aggregate?

To recover an inconsistent aggregate, the following tools can be used:

What it does:This tool is used to perform a consistency check on WAFL metadata. It identifies and attempts to fix WAFL inconsistencies in aggregates.

When to use:Run wafl_check after identifying WAFL inconsistencies to repair minor metadata issues.

1. wafl_check

What it does:This tool repairs WAFL inconsistencies by reconstructing metadata. It is more powerful than wafl_check and should only be run under NetApp Support guidance, as improper use can result in data loss.

When to use:Use wafliron for severe WAFL inconsistencies that cannot be resolved by wafl_check.

2. wafliron

A. file check:

This is not a valid NetApp tool.

C. wafl snapiron:

While similar in name, snapiron is used for snapshot recovery, not aggregate recovery.

Why Other Options Are Incorrect:

"ONTAP Aggregate Troubleshooting Guide" details the usage of wafl_check and wafliron.

NetApp Support documentation provides guidelines for recovering inconsistent aggregates.
